Tips and Expert Advice

To ensure your Arborvitae trees grow to their full potential, here are some practical tips and expert advice:

1. Choose the Right Variety:
   • Different Arborvitae varieties have different growth rates and mature sizes. Research and select a variety that suits your specific needs and growing conditions. For example, if you want a fast-growing privacy screen, consider 'Green Giant.' If you prefer a more compact and formal hedge, 'Emerald Green' might be a better choice.
   • Consider your local climate and soil conditions when selecting a variety. Some Arborvitae are more tolerant of drought or cold than others. Consulting with a local nursery or arborist can help you make the best choice for your area.
2. Proper Planting:
   • Proper planting is crucial for establishing healthy Arborvitae trees. Dig a hole that is twice as wide as the root ball but no deeper. This allows the roots to spread easily and establish themselves in the surrounding soil.
   • Before planting, amend the soil with organic matter such as compost or well-rotted manure. This improves soil drainage, aeration, and nutrient content, providing a favorable environment for root growth. Gently loosen the roots of the Arborvitae before placing it in the hole.
